GRAIN-LIFTING DEVICE FOR HARVESTERS.

Specification of Letters Patent.

Patented. Oct. 22, 1907.

Application filed April 27,1907. Serial No. 370,570.

To all whom it may concern: 7

Be it known that I, WILLIAM WEBBER, a citizen of the United States,residing at Chicago, in the county of Uook and State of Illinois, haveinvented a new and useful Improvement in Grain-Lifting Devices forHarvesters, of which the following is a complete specification.

In harvesting down, tangled and heavy grain it is necessary to lift thegrain from the ground before cutting same, and to do this grain liftingfingers are secured to the finger bar and made to project forwardlytherefrom. Such devices and their function are well understood in theart.

The lifting fingers heretofore employed have not been sufficientlyelastic in their vertical movement and were not adapted to be readilyattached and detached to and from the finger bar of the harvester, andhence were to this extent objectionable.

The object of the present invention is to relieve the construction ofthe above mentioned objections, to insure a proper connection betweenthe vertically movable arm of the lifting finger and the correspondingguard finger when in operation, and to provide a finger which is welladapted to be applied to practically all types of harvesters.

Referring to the accompanying drawingsFigure 1 represents a sideelevation of the device applied to the finger bar and guard of aharvester, the finger bar being shown in section. Fig. 2 is an enlargedplan of the rear end of the device shown in the preceding figure. Fig.3is an enlarged side elevation of the rear end of the grain lifter withthe parts in their normal working position as shown in Fig. 1. Fig. 4isaview corresponding with Fig. 3 but with the arm raised to disengagethe thimble from the guard. Fig. 5 is a transverse section taken throughthe guard adjacent to the rear end of the thimble, as indicated by theline 55 in Fig. 3; Fig. 6 is a detail plan of the thimble. Fig. 7 is aperspective view of the supporting block with the grain elevatordetached; and Fig. 8 is a detail section taken on the line 88 of Fig. 2,and is designed to show the projection on the trunnion for holding samein position on the supporting block.

In the drawings the harvester finger bar is designated by l, and to thisare fixed the guards 2. On the finger bar 1 is secured the'block 3,which forms a pivotal support for the forwardly projecting arm 4, whichis formed preferably of an angle bar. To give lateral rigidity to thearm, it is made to connect with the block 3 by means of a yoke 5, andboth the block and yoke are given considerable width, as shown in Fig.2. Recesses, as 6, are formed in the ends of the block 3, into which fitthe yoke trunnions 5 the forward side of one of the recesses being cutaway, as at 7, to enable the trunnions to be introduced into therecesses and the yoke thereby attached. Shoulders 8, formed integralwith and projecting downwardly from the under side of the trunnions,serve to hold the same at the upper side of the recess, in whichposition the arm 4 is interlocked with and effectually prevented frombecoming detached from the block 3. On the forward end of the arm 4 ispivotally mounted the lifting finger 9, which is made adjustable inheight at its rear end by moving the lower end of the connecting strap10 to a registering position with respect to any one of the series ofapertures 4 in the bar 4 and securing with the bolt 11. j

To yieldingly sustain the forward end of the lifting finger and toproperly deflect the grass below the guard 2, whatever the elevation ofthe arm 4 in its working position, a thimble 12 is mounted on the arm 4and engages with its rear end the point of the guard 2. A coil spring 13is interposed between the thimble and an upwardly projecting lug 5 onthe yoke 5. The angle bar forming the arm 4 is provided with the slots 4and 4 and through the slot 4 projects the upper forward end 12 of thethimble. A slot 12 is formed in said end which engages the bolt 14, thusproviding not only a pivotal movement but also a longitudinal movementof said thimble. Through the slot 4 extends the rod 13 which connectsthe thimble with the spring 13, and through this same slot projects alsothe lug 12 which is formed on the rearward end of the thimble. This lug12 contacts the rear end of the slot 4 and limits the rearwardlongitudinal movement of the thimble 12. In normal working position thethimble will occupy the full line position shown in Fig. 3, in which theforward end of the slot 12 will bearagainst the bolt 14. The arm 4 willthus be permitted to swing vertically a limited amount withoutdisengaging the thimble 12 from the guard 2, the extent of this movementbeing determined by means of the shoulder 12 on the lug 12 and asindicated by the dotted line position of Fig. 3. If it is desired todisengage the attachment from the finger bar, the arm 4 is raised fromthe dotted line position of Fig. 3 and the thimble 12 is pulledforwardly slightly beyond the position shown in Fig. 4. After the armhas been raised to substantially a vertical position the shoulders 8 onthe trunnions 5 will have turned suffieiently to permit the trunnion todrop down and the yoke removed.

What I claim as my invention, and desire to secure by Letters Patent,is:

1. In a grain lifting device for harvesting machines, in combination, asupporting block adapted to be secured to the finger bar of a grainharvester, a forwardly projecting arm pivotally mounted thereon, arearwardly and upwardly extending lifting finger fixed to the forwardend of said arm, means engaging the point of the harvester guard andpivotally connecting with the forwardly projecting arm for deflectingthe material beneath the guard. and a spring operating to hold theforward end of the arm down in its working position.

2. In a grain lifting device for harvesting machines, in combination, asupporting block adapted to be secured to the finger bar of a grain,harvester, a forwardly projecting grain lifter pivotally mountedthereon, a thimble pivotally mounted on said lifter and arranged toengage the point of a guard on the finger bar, and a spring operatingboth to hold the grain lifter down in its normal working position andthe thimble in engagement with the point of the guard,

3. In a grain lifting device for harvesting machines, in combination, asupporting block adapted to be secured to the finger bar of a grainharvester, a forwardly projecting grain lifter pivotally mountedthereon, a longitudinally movable thimble pivotally mounted on said armand adapted to engage the point-of a guard on the finger bar, and aspring operating both to hold the grain lifter down in its normalworking position and the thimble in engagement with the point of theguard.
